No. 405,679 Claims priority, application France, Oct. 25, 1963, 44,127, Patent 1,381,485 7 Claims. (Cl. 24218) ABSTRACT OF THE DISCLOSURE A textile winding frame has a drive shaft rotatable about a fixed axis and connected by a universal joint to a swingable shaft section mounted in a frame that provides a slideway on which a carriage slides parallel to the swingable drive shaft. The bobbin is carried by the carriage for rotation about an axis perpendicular to the direction of carriage sliding, and the frame can be fixed in any swung position so as to incline the axis of the bobbin to the direction of reciprocation of the thread guide. The carriage slides as the spool grows, and the spool can be made cylindrical or conical by selecting a swung position of the frame.

In existing winding frames, the displacement of the head resulting from the growth of the spool is obtained, as a general rule, by a pivotal movement either of the head carrying the spool or of the group of members carrying the oscillating motion.

This pivotal movement is detrimental because it has the consequence of modifying the characteristics of the common tangent to the support roller and the spool proportionally to the growth of the latter.

Besides this it limits the final diameter of the spool to the space between the axis of the latter and the pivotal axis of the oscillating motion.

With the object of palliating this disadvantage, the first characteristic of the present invention is to mount the head to slide, in the manner of a carriage, upon guides which ensure its displacement in a single plane relatively to the support roller or yarn guide.

On the other hand when it is desired to modify the shape of the package being wound, for example, from that of a cylinder to that of a cone whose angle is selected by the user, one is forced to change several parts of the winding frame, which necessitates dismantling, re-assembling and adjustments amounting to a series of long and delicate operations.

According to another feature of the invention, the said carriage :and its guide means are collectively pivotable about a shaft and lockable in the selected position, which modifies the angular displacement of the carriage with reference to the support roller (or yarn guide) and this likewise modifies the profile of the package.

In this way it is possible, solely by replacement of the intermediate member supporting the conical or cylindrical tube on which the yarn is to be wound, and by the simple adjustment of the inclination of the guides, to alternate between one shape of package and another involving different winding angles.

According to a preferred embodiment, the carriage of such a winding frame includes a splined shaft which transmits rotary motion to the spool support through bevel gearing, the splined shaft itself receiving its movement from the fixed block of the winding frame by means of a Cardan coupling which permits the inclination of the carriage to be adjusted without affecting its movement.

The fixed block comprises the cam controlling the yarn guide, the variable-speed system which causes the oscillation, and the usual accessories, the controls for lubrication, yarn-breakage, etc.

The invention envisages other characteristics used in combination or otherwise, and more particularly the following:

(a) The Cardan coupling includes a shell formed with internal teeth and having a hemi-spherical profile so that it allows universal motion of the assembly and the transmission of its rotary movement to a driven gear whose teeth have complementary profile.

(b) The guides are enclosed within a bellows assembly to protect them from dust.

(c) A toroidal joint ring seals the Cardan transmission.

The invention will in any case be readily understood with reference to the schematic drawing attached hereto, purely by way of example, in which:

FIGS. 1 and 2 are plan views of the assembly as arranged for cylindrical or conical winding respectively.

FIG. 3 is a perspective view of the driving mechanism proper, and

FIG. 4 is a sectional view of the Cardan transmission.

In these drawings, the stationary body indicated at 1 is provided with the cam 2 controlling the yarn guide 3, means 4 for oscillating the latter and its support roller 5 (FIG. 1) or alternatively for oscillating the yarn guide 6 (FIG. 2).

The body likewise contains the driving means for the spool carrier 7.

The drive is effected by skew gears 80, 8b, a Cardan joint 9, a shaft 10 and further skew gears 11a, 11b. The shaft 10 is splined and the gears 11:: can slide longitudinally thereof while being rotatively driven.

The skew-gears 11a, 11b, as well as the shaft carrying the spool 7 are mounted in a gear-case 13 which is arranged to slide in the manner of a carriage on guides 14 having end plates 15a, 15b so that the said gear-case, with its contents, can move on the said guides proportionately to the growth of the spool 7 while remaining parallel thereto.

The carriage is pivotable about an axis 16 represented by the Cardan joint 9 and engages at its other end with a fixed part 17 of the frame through which a runner 18 on the plate 15b can slide.

By causing this carriage or slide frame to pivot about the axis 16, the angular position of the shaft of the spool carrier 7 in relation to the axis of the support roller 5 can be adjusted to allow the shape of the paclcage being wound to be changed from a cylinder to a cone of any desired angle.

Once this adjustment is effected, a locking device in the form of a clamping screw 17a ensures its permanence.

To prevent any fluff or dust penetrating into the abovementioned mechanism, two bellows 19 are provided.

FIG. 4 shows the details of the Cardan joint 9. The shaft 20 of the gear 8b rotating in the bearings 21 of the stationary body 1 has fixed thereto a hemi-spherical shell 22 upon whose exterior the end plate 15a of the guides 14 can pivot within the bearing housing 23 and the toroidal sealing ring 24.

This shell has internal teeth 25 whose profile is curved in an arc centered at the pivotal .axis of the shaft 20 and which engages with the toothed rim of a part-spherical head 26 keyed to the end of the splined shaft 10 and universally movable within the shell 22. A member 27 centers the head 26 in end plate 15a. An elastic member 28 closes the joint fluid tightly. A plate 29 covers the elastic member 28 and holds it in place. The shaft 10 is journalled for rotation at its other end (not shown) in the other end plate 15b.

As is obvious and has been previously explained, the invention is in no way limited to the single embodiment described above; on the contrary it includes all Variants of such embodiment.
